Least Common Multiple of 21, 531, 402

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 21, 531, 402 by common division method
• Least Common Multiple of 21, 531, 402 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 177 x 134 = 498078

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 21,531,402 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,531,402) = 3

common factors(in case of two or more numbers have common factors) = 3

GCF(21,531,402) x common factors =3 x 3 = 9

LCM(21,531,402) = ( 21 × 531 × 402 ) / 9

LCM(21,531,402) = 4482702 / 9

LCM(21,531,402) = 498078

∴ Least Common Multiple of 21,531,402 is 498078

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 73, 387, 333
• LCM of 88, 867, 789
• LCM of 77, 297, 906
